Immunofluorescent imaging of HAECs using VE-CAD (red) and p120 (green) antibodies was performed 12 h after DMSO (control), Torin-2 (100 nM), or EVL (500 nM) treatments. White arrows denote interendothelial gaps. White bar indicates 50 μm. EVL treatment increased VE-CAD mobilization from the membrane into the cytosol (relative to DMSO) with evidence of intracellular deposits and interendothelial gaps, whereas in DMSO-treated cells, there was colocalization of p120 and VE-CAD (yellow border) with no evidence of gap formation. In Torin-2-treated cells, there was evidence of colocalization of p120 and VE-CAD at cell borders with minimal interendothelial gap formation.
